what injectors are these?
 
1 Attachment(s)
I read online they might be supra 440cc or Mazda 360cc. How do you tell without a flow test? They are in a 1.6. https://www.miataturbo.net/attachmen...ine=1401322159

There should be a number stamped on the plastic on the side of the injector...something like 195500-3350 or something like that.

Thanks I'll check that out

Those look black to me. I'd assume they're out of the 323 GTX and are 360cc, based of this site:

Fuel Injectors - Miata Turbo FAQ

I'd also move on to a better injector. Recently upgraded to RX8 injectors on my car and NB2 injectors on a friend's N/A NA. Impressed with the results, and happy I'm done with those giant boxes called injectors.

That is the site where i found my original information to ask the question. I still have to look to find the serial number on the side of the plastic. Do you think moving to the rx7 purple top would be good for 250whp? If so i need to get my hands on some of those.

He said to move on to a better injector. He did not specifically say to move on to a bigger injector. Just a better one. Size is up to you.

With the price of a set of RX-8 yellows being in the sub-$100.00 range, I can see absolutely no justification for not finding a set of them over any other "budget" injectors.

Wow that seems like a good deal. Ill try to find some of those. Would they be able to support 250whp? Id like to make a minimum of 250whp and anything over is nice but not needed.

concealer404 05-29-2014 12:27 PM

Not sure. I don't think anyone has asked that question before.

If you have some you'd like to sell for sub $100, please let me know.

concealer404 05-29-2014 01:00 PM

Brand new ones are $160. Just do it.

pdexta 05-29-2014 01:06 PM

These are the ones you guys are talking about right?

450 cc Injectors Mazda Miata

Where are you finding them so cheap? I've been looking for cheap injectors for a couple months and all I can find is people wanting $150 for some rusted up 1988 N/A RX7 injectors.

They can be purchased on ebay sans Begi Tax.


Example: Here's a set of 550s i've been watching: http://cgi.ebay.com/ws/eBayISAPI.dll...m=380915400089

The yellows can be found for the same if not cheaper. I saw a set go a few weeks back for $152.

These are reman, but the new yellows seem to hover in the $160-$180 range.

dieselmiata 05-29-2014 02:11 PM

Log on to the RX-7/8 forums and wait. I picked mine up for $100.00 and they had just been flow tested.

Those flow tests just look too good to be true.

Be as it may, i can 100% guarantee that they test better than whatever old crap EV1s you were talking about getting earlier.

Reverant 05-29-2014 02:17 PM

The black ones above have a square connector, so they are not from the 323, which has the proper connector to be PnP. These may be low impedance, so beware.

I might end up getting those. I have a guy who wants to sell me deutsworks 440cc for $150. should i get the 550cc instead off ebay? I am trying to make around 250whp

Your question is impossible to answer as posed.

It's almost like you're incapable of doing any sort of research yourself.

These might be the low impendence supra injectors i was reading about. I read that it was either 360cc mazda injector or a 440cc supra injector. Those were the only two black top injectors i could find for mazda. It said that the supra was low impendence and not plug and play.
